The Bamford-Stevens reaction of diphenaldehyde bis-tosylhydrazone (4), examined in five different procedures, afforded phenanthrene as main reaction product. 5H-6-Azadibenzotetrazolocycloheptene (6) was obtained as by-product (32percent) in aprotic basic reaction conditions.The reaction mechanisms are discussed.Formation of a tetrazole during Bamford-Stevens reaction of a bis-tosylhydrazone seems to be observed for the first time.
